Heavy-Grip Rubber Wheels for Sumo Robot Traction and Power Transfer

The JS4030 Rubber Wheel Pair is built for robot makers who need more grip, more contact area, and stronger wheel structure for larger or more aggressive robot projects. JSumo presents this model as a high-quality sumo robot wheel used in competition-style builds.

These wheels use beautifully machined aluminum hubs with a strong rubber tire that is directly molded to the hub by vulcanization, helping create a stronger and harder wheel assembly for demanding robot use.

Why you'll love it

• Strong traction: Rubber tire is built for powerful robot grip
• Vulcanized construction: Helps make the tire-to-hub connection stronger
• Competition oriented: Recommended for sumo robot projects
• Large contact area: Useful for higher-force pushing robots
• Machined aluminum hub: Better rigidity and wheel stability

What you can build

The JS4030 is ideal for sumo robots, combat robots, magnetic robot platforms, and custom drive systems that need more traction and a wider wheel footprint.

Starter bundles

Pair it with a gearmotor, motor mounting hardware, a robot controller, and a strong robot chassis for a complete drive setup.

Recommended add-ons

Useful add-ons include spare setscrews, mounting screws, robot gears, and high-current motor drivers for more powerful robot builds.

Technical specifications

Pinout & usage notes

These wheels are best matched with robots that can take advantage of their wider profile and traction. Make sure your shaft size, mounting pattern, and motor torque are compatible with the wheel system you plan to use.
